We offer ETP Equipments. The various plants and equipment offered by us are capable of treating water pollution caused by rampant industrial and Population growth.
High Rate Solid Contact Clarifier
Process: Treats raw and waste water, producing clarified water of highest quality the principle here is that if preformed flocs particles are feed back to mix with the incoming water, the microfloc particles in the raw water are captured much more rapidly and efficiently. The sludge is older and therefore more consolidated. Surface rating for these types of clarifiers are higher (3 – 4 m/h), coagulant usage less and wider range of water qualities can be tolerated. Applications:
Clarification of surface water
Lime soda softening
Removal of colloidal silica
White water recycling
Primary (physico-chemical) treatment of waste water
Removal of heavy metals in the chemical and automobile industries
Principles Of Operation:
Colloidal particles of color, turbidity and suspended solids brought together by coagulants
Coagulated particles made heavy by flocculants
Heavy flocs made to settle down
Substantial concentration of previously formed flocs, recycled for ‘seeding effect’ responsible for speedy flocculation
Uses up flow design to move water into settling zone for clarification
Energy efficient design
Removes suspended solids and turbidity by a physico-chemical
Uses minimum time, space, chemicals
Uses alum, FeSO4, FeC13, NaAlO2 for coagulation
Uses polymer for flocculation
Uses lime and Na2Co3 for chemical precipitation
Intimate and prolonged contact with large quantities of previously formed flocs.
Entire bottom used for settling and collection of dense floc precipitates
In-built flash mixer, floculator and thickening pickets concentrate the settled sludge.
Tangential water inlet
Slowly moving multiblade scraper carry settled flocs into the sludge.
Mechanisum are suspended from fixed bridge.
Flash mixing and slow speed agitation require low retention time.
Simple to operate
Circulation flow can be varied to suit different loads
Low power consumption, Rapid chemical and more complete reactions
High sludge Consistency
Provides greater flexibility
15 – 20 % reduction of chemical required
Thorough contact with solids regardless of thorough put
Using SS steel belt of 0.12 MM thickness (same as Abanaki, US) this model and belt is with guarantee for workmanship. Even replacement cost is also just around Rs. 600 approx.
Belt type oil skimmers fitted on stand mechanism to lift the oil up from underground tanks of ETP and other applications and to collect the oil directory into 200 Liters. Drum kept on the earth we use imported oleophelic polyurethane high efficiency belts.
Steel Slat Belt Oil Skimmers using SS Steel Slat of thickness 2.5 mm for applications like coolant degreasing tank, machine tool, washing machine ETC capable of working at high liquid temperatures like 100 degree centigrade and in harsh chemicals.
Hydraulic trolley loaded belt type portable model with adujustable depth to make suitable for different tanks. ALL small belt type models are having builtin decanter tray arrangement to further separate oil from the collected Skimmed Oil and water/coolant ETC mixture to return back the coolant, Washing liquid ETC back to the tank only pure oil is collected.
Depth is the distance between skimmers mounting base and the lowest liquid level in the tank or it is the distance between your tank top where you are going to fit the skimmer and the lowest liquid level of the tank.
Filter presses are extensively used to separate solids from liquids in a wide range of applications. The liquid solid mixture is pumped into the filter press, which is made up of a number of recessed filter plates forming chambers. The plates are supported in a fabricated steel frame and are held closed by a force exerted from a hydraulic ram mounted in the frame work at the end of the machine. Each filter plate is covered by a filter cloth that retains the solid particles, but allowing the liquid to pass through and exit through the ports in the filter plate.
Chemicals: Basic, Organic and Inorganic chemicals.
Pharmacuiticals: Antibiotics Bulk Drugs, Intermediates, and Syrup.
Unit is conical tank available in MS, SS, and FRP provided externally with a supporting structure, valve and piping to direct and control flow of water during treatment and for cleaning. Above unit are having design options for Chemical Mixing, system with agitator, Chemical dosing system etc. To control and measure flow during normal and cleaning operations, flow indicators are provided at an optional cost.
This tank will be equipped with fix type slow speed surface aerators with inlet and outlet arrangement. Here effluent will be aerated by means of fixed type slow speed, surface aerators mounted on suitable RCC platform. The surface aerator will be connected with suitable HP motor through speed reduction gear. The submerge of the aerator will be such that maximum aeration and mixing is achieved. Diffused Aeration System:
High performance fine bubble Membrane diffuser for waste treatment aeration. Unique open-end tube design diffuser allows waste water to completely fill the diffuser support tube, thus eliminating diffuser buoyancy and not allow diffuser to bounce during operation and there is not breakage / failure of nipple end connection.
High Oxygen transfer efficiency.
Self cleaning operation
Fine bubble formation
Intermittent operation without water backflow
No moving parts-assures safety
Unbreakable, light weight & heavy duty membrane to withstand high pressure.
Economic operation due to low investment & operation Cost.
FMR system is a Single Tank Design Unit consisting of:
FMR aeration tank with floating media
Chlorine Contact Tank
Treatment Scheme With FMR: (Schematic diagram / Process Flow Sheet)
Features of FMR Media:
High Surface Area
High physical & chemical resistance
Low Annual Losses (3-5%)
Good biomass retention capability
Significant reduction in space requirement due to its single tank design and compactness
Reduced power due to elimination of sludge recirculation
No moving mechanical parts, less maintenance
Increased SRT and hence well nitrified effluent and low sludge volumes
Easy up gradation and extension of existing waste water treatment plants
Advantages over FAB:
FMR has fewer tanks than FAB. Hence, it is more compact
FMR occupies less area than FAB (FMR requires 25% less area than FAB)
FMR adopts lamella technology for settling which is more efficient and superior than tube settler of FAB
Lamella plates can be easily cleaned while the unit is in operation. Tube settler cannot be cleaned online
Tube settlers are more prone to clogging
Advantages over Eco-Cell:
FMR is a biological process which is close to the nature. ECO-CELL is a physico-electro-chemical process requiring to dose various chemicals like polymers, salt and consumable electrodes. Life of electrode is 2 to 3 months approx.
FMR does not alter TDS level of sewage whereas ECO-CELL increases TDS of the treated sewage which is not good for the plants
As ECO-CELL depends only on chemcial process for BOD/COD reduction, it cannot efficiently remove them and hence cannot produce high quality treated sewage
The electrodes gets scaled and becomes inefficient in its performance requiring very frequently maintenance.
Introduction: This paper will discuss the application of membrane bioreactors (MBRs) to treat domestic waste for small communities, either for discharge or for reuse. The use of membrane bioreactors for both domestic and industrial wastewater treatment has expanded significantly in the last few years. This paper will discuss the MBR process, and then highlight two case studies that demonstrate the applicability of the MBR to small communities. Features:
