RDA developed together by research institute of chemical technology and research center of pulp and paper. As a sole equipment a new papermaking process analyzer that analyze the complex and huge papermaking process. Plays a core role in analyzing and optimizing characteristics of papermaking process in research institutes and papermaking business circles. Automation through artificial intelligence from materials supply to sample production. The Auto sheet making facility makes the system ideal use in understanding the effect of chemicals on Paper quality in Lab itself.

The instrument uses streaming current measurement to maintain proper electrokinetic charge in the treated water. Effectively it responds to change in raw water characteristics i.e. turbidity, color ,PH etc. .This allows operator to make necessary adjustment of coagulant feed to maintain for treatment. The automation saves the cost of chemicals / coagulant by preventing overdosing.

Turbidity is a function of the light transmitted/absorbed by water having suspended solids. However it has various limitations and is not accurate enough. For example, 2 waters having same turbidity may require different quantity of coagulant dosages because of difference in charge density on the suspended particles. Thus, measurement of streaming current/charge on the suspended particles helps accurately determine the charge demand to neutralize suspended solids and optimize coagulation. The system for online control of turbidity consists of Online measurement of streaming current, solution preparation of coagulant, metered dosing of coagulant based on output from streaming current monitor, online dilution of coagulant and online turbidity monitor (optional) to measure turbidity of clean water.

As machine speeds in paper coating and converting operations steadily increase, papers are stretched more than before, eg. In the printing press, which may result in misregister problems. Because of this, the paper quality has to be assessed prior to upgrading and converting. However, traditional static test methods such as wet tensile, COBB, or HST tests fail to satisfactorily describe the converting behavior. What is needed for quality assurance is more detailed test methods which give close-to-reality results. This is where the WSD Analyzer comes in-to measure the wet stretch dynamics of paper.

It reveals the behavior of paper materials during printing and impregnating processes. The results provide information about the composition of papers or liquids such as inks or impregnating resins, so that industrialists can work on optimization.

Laboratory Flocculator has been specially designed for use in water & chemical treatment plants and it enables the plant operator to correctly estimate the dosing of alum, other coagulants and flocculants for treatment of water and thus avoid wastage of costly chemicals.

Chemists/Operators in Water Works, many a times face problems of regulating proper dosage of chemicals in the plant due to variations of the inlet water quality. Underdosing results in plant being disturbed and overdosing is normally done to avoid variations in the output of the equipment. This equipment allows the operator to simulate plant conditions in the laboratory enabling easy optimization of dosage.
This equipment is also essential to do comparative study in laboratory on the performance of various chemicals on the water/ waste water to be treated.

Production and converting processes which rely on interactions between liquids and materials such as paper, paperboard, textiles etc. are highly complex in nature. For the purpose of quality control or studies into material properties, current methods utilize these interactions to derive data on specific paper and liquid parameters and ultimately on the manufacturing or converting processes themselves. However, these methods normally give only simple numerical values without allowing for the dynamics of liquid penetration. More often than not, the results obtained can only be assessed subjectively. In the areas of product development, process optimization or quality assurance the Penetration Dynamics Analyzer (PDA) provides a unique method for quick and easy measurements giving reproducible results.

This instrument has been developed to quickly and accurately determine the influence of chemicals on filtration properties by automatic analysis of drainage and retention of fiber suspensions.

The instrument can be operated very simply from the computer program. This program allows all of the relevant data to be entered. A mixing profile can also be programmed, that can be used to simulate process conditions.

After setting the necessary parameters, you are requested to feed the material to be measured into the instrument, following the mixing profile will run its program. When this is completed, the valve will automatically open and filtration will take place. The amount of filtrate is continuously measured with approximately 5 samples per second. This is displayed in a graph showing the amount of filtrate as a function of time. The computer program can be used to compare all of the graphs by displaying them in the window. It is possible to add all sorts of parameters to the graph, so that comparable graphs are created, such as the dosed amount of chemicals compared to the dehydration velocity.

Rishfloc Range of flocculants consists of polymers & copolymers of Acrylamide. These are water soluble polyelectrolytes and have very high molecular weights. The range includes Anionic, Nonionic and Cationic polymers in powder, emulsion as well as in solution form.

Flocculation is the agglomeration of tiny particles into large units.

These products find use in dewatering applications in centrifuges, decanters, etc. Due to good floc formation on use of Rishfloc flocculants, it is possible to get clear centrate, increased solid content in cake and also increased throughput and efficiency of the equipment.

The excess paint sprayed in automobile paint booth is normally captured by water curtains and these paint particles have to be separated from water as sludge, leaving clear water which is recycled, to strip off further airborne paint particles. This can be achieved effectively by the use of the Detachyfying Agent (DTA). DTA thus causes effective separation of Paint particles entrained in water and renders water for reuse. In some cases, it is possible to recover the excess paint (over spray), which provides more benefit to the customer.

Rishlyte dispersants are phosphorous-free, low molecular-weight polymers, and are non-volatile and practically stable to hydrolysis at the temperatures in question. These polymers act as powerful dispersants in ceramic slurries and prevent the sedimentation of the suspended matter. Good amount of the inorganic dispersants viz STPP can be easily substituted through the use of these products.

Presently conventional coagulants (i.e. salts of Aluminium or Iron) are used to precipitate dissolved solids and also to settle suspended matter in many effluent treatment plants. These pose problems of carry over finely divided flocs of aluminum hydroxide or ferric hydroxide into the clarified water and produce bulky sludge having a high water content. This increases the sludge handling and disposal costs.

Due to drop in pH on use of these coagulants, often further chemicals are needed to counter the effect.

Rishlyte range of coagulants for industrial waste water treatment consists of 'nontoxic' cationic polymers which replace inorganic coagulants (viz Alum, PAC, Lime, Ferric salts) and also reduce cost of treatment.

Numerous other benefits include -

a) Reduction in sludge volume and desludge frequency.
b) Reduced sulphate/ chlorides in the treated effluent and negligible drop in pH of treated water.
c) Reduction in corrosion in coagulant addition pipeline and pump.
d) Automated dosing & controlling of suspended in plants is possible with Rishabh's coagulants
e) Savings in labour and electricity costs

Rishlyte 8005 series is used to decolourise effluents containing anionic, direct or reactive dyes. It is a liquid product, therefore easy to handle and is suitable for use in dyehouses and in municipal biological sewage treatment plants. It is Compatible with the usual inorganic and organic precipitants.

The amount required is 0.1-1 ml/L Rishlyte 8005, depending on the amount of unfixed dyestuff and the desired degree of decoloration. In the case of unfixed direct dyestuffs, smaller amounts are required. The degree of decoloration is determined by measurement of extinction.

Combination with other organic flocculation auxiliaries (e.g. polyacrylamides) and inorganic salts (e.g. iron salts) is possible. However, these products have hardly any effect on the flocculation of reactive dyestuffs.

Rishlyte 9231 and 9232 are also used to remove colour from industrial effluents and function as good precipitating coagulants.

Drainage aids are linear very high molecular weight, Copolymers of acrylamide and acrylic acid/cationic monomers. These products are structured copolymers of acrylamide for better paper formation and have excellent solubility and negligible gel content.

The basic purpose of these products is to improve drainage and therefore reduce water content in the paper web, resulting in -

a) Saving of thermal energy/ steam required for drying of the paper

b) Possibility of increasing machine speed.

Due to shortage of softwood and the replacement by hardwood as well as the strongly increased consumption of waste paper as a secondary fibre source deterioration in paper strength are inevitable. Further strength reducing factors are lower single fibre strength that were caused by chemical or mechanical damage. A further factor is a bad fibre to fibre binding.

RISHLYTE Dry Strength Additives are synthetic organic polymer derivatives. They strengthen and multiply the binding between fibres and fibres as well as fibres and fillers and therefore, improve the structure in paper.

The ADVANTAGES are improved strength properties of paper & paper board viz. breaking length, stiffness, burst as well as ply bond strength. An improvement in Retention is a desired side effect. Different grades of products have been developed for acid, neutral and alkaline paper making.

The Rishlyte DFA series consists dye fixing agents which are formaldehyde based & formaldehyde free. The Rishlyte DFA series is used as an after-treatment in the washing stage of the dyeing process for direct and reactive dyestuffs.

Greater Fastness
Lower Dye Transferability
Increased Chlorine Stability
Reduced Bleeding
Enhanced UV Stability
Effective over a wide pH range
Easy to handle, non-hazardous, liquid.

The flocs formed when alum or PAC are used as coagulants for raw water treatment, are weak in nature, fluffy and have high moisture content. When some of these flocs carry over along with the clarified supernatant on to the sand bed filter, the flocks break up and clog the flow channels resulting in frequent backwashes.

On use of Rishlyte for the treatment of raw water, the flocs formed are stronger and compact and add to the filter bed, thereby increasing the clarity of filtered water. These flocs do not break nor clog the filter, thus improving efficiency of filtration and increasing the filter run. Increase in filter run upto 3 to 4 times have been observed, resulting in huge savings of water, labour and electricity.

Rishfloc Range of flocculants consists of polymers & copolymers of Acrylamide. These are water soluble polyelectrolytes and have very high molecular weights. The range includes Anionic, Nonionic and Cationic polymers in powder, emulsion as well as in solution form.

Flocculation is the agglomeration of tiny particles into large units. It therefore, finds application in many different industries and helps in achieving clear supernatant, results in fast settling and increases capacity of clarifiers and clariflocculators apart from noticeable cost reduction.

These products also find application in dewatering applications in centrifuges, decanters, filters etc.

In open and closed cooling systems micro-organisms cause disturbances in industrial processes and damage to the material through corrosion. Slime forming and corrosive type of bacteria are the main causes of the following detrimental effects :

- Contamination of heat exchanger surfaces or blockage of pipes
- Corrosion under micro-biological deposits.

In order to inhibit or destroy the micro-biological growth, highly active but toxic and ecologically suitable biocides are often used.

Rishlyte 8094 overcomes these toxicity problems and prevents shutdown losses of equipment and results in dispersing of slime deposits and further prevents formation and growth of slime deposits in pipelines.

Presently conventional coagulants (i.e. salts of Aluminium or Iron) are used to remove turbidity in water. These pose problems of carry over finely divided flocs of aluminum hydroxide or ferric hydroxide into the clarified water and also produce bulky sludge having a high water content.

During monsoon season when turbidity suddenly increases, numerous problems are faced in treatment of water with conventional chemicals e.g. Alum and Lime.

Retention aids bind fillers and fines to the fibre so they can be retained in the sheet. If the fillers and fines are not retained with the sheet, they pass through the wire, where they create collection, disposal, and deposit problems. Retention aids also fix dyes to the sheet.

Retention mechanism is mainly by reduction or neutralization of the surface negative charge of colloidal particle, fillers and fibres thereby enabling them to coagulate and aggregate on to large fibres by bridge formation.

Rishabh's Retention and Drainage Aid Product Line consists of 25-30 products in powder and emulsion forms for optimal working in a system.

Product Charge
a) Anionic - medium & low
b) Cationic - high, medium & low

The working pH range is 4 to 9 and apart from increasing the First pass retention, these products also help increase the ash content in paper resulting in reduced cost of paper making.

These are complex cross linked and formulated polymer compounds which are specially made for Size Press to improve stiffness, smoothness, and to some extent other surface properties of paper. Improved wax pick & printability has been observed through application of Rishlyte 8514 & 8523 at size press. Normally doses vary from 1 to 2.5 kg per ton of paper depending on the end stiffness results desired. They do not interfere with efficiency of other chemicals and can be used for food grade papers. While some Lab trials are indicative, plant trials are suggested to know the results in dynamic conditions.

The products are mainly useful for increasing stiffness of paper & board made from waste paper, rice & wheat straw, bagasse, hardwood and bamboo. In some cases high value raw material incorporated in the furnish mainly for increasing stiffness can be replaced. Since it is just added as supplied, it is very easy to use.
