Design Guidelines

• Depth to width ratio: A minimum depth to width ratio of 0.3 to 0.5 is specified so that separator does not increase droplet rise time to reach the water surface.
• Length to width ratio: A minimum length to width ratio of 5:1 is specified for API separators to keep flow characteristics homogeneous, reducing short circuiting effects.
• Maximum channel width and depth: The maximum API separator channel width is 20 ft; maximum depth is 8 ft.
• Horizontal velocity: Maintaining a horizontal velocity of no more than 3.0 ft/sec to minimize turbulence and its interference with the separation process..
• Oil droplet size: Most oil droplets in refinery wastewaters are 150 micron or larger. The API design standards were based on this droplet. Droplets smaller than 150 micron typically escape API separators and further treatment processes, unless allowances are made in the sizing of the API separator to remove these smaller particles.

Lamella settlers are basically cross flow plate separators designed for removal of settle able solids. The water containing solids flows in the horizontal direction between the closely spaced plates in the plate pack. Completely laminar flow conditions are established while the water flows across the plate packs from the inlet to outlet side. Solid with higher density than the carrier fluid will settle down into the sludge compartments of the separator, which is sloped compartments to facilitate removal of solid particles.
The number & size of the plates is governed by the water flow rate & settling velocity of the solids, which in turn are proportional to the diameter of the solids to be settled. The distance between the plates is depending upon the concentration of the solids sludge in the raw water. The plate distance can be varied, usually between 20-50 mm, to allow for the different sizes of the settling particles & to prevent clogging of the plate packs.
The systems are fabricated in the mild steel & other materials are available on request. All K-Pack separators are custom built with respect to the number of plates in the pack, the length of the plate distance between the plate and the plate incline. The incline of the plate is set between 45 and 60 degrees depending upon the general nature of the oil and/or the sludge.(density, velocity, concentration). The systems are fabricated in the mild steel, and other materials are available on the request. The oil separators are standard with oil and skimpy and 45 degree shaped compartment. The solid separators are optionally with a shiftless conveyor in the sludge compartment.
They are mostly used in industries like:

• Mineral oil industry.
• Edible oil industry.
• Metal industry.
• Ceramic industry.
• Galvanic industry.
• Mines.
• Sand separation after washing of contaminated soil.
• Food industry.

Dissolved air flotation unit is a gravity separation process where the separation of two phases is achieved by increasing the specific gravity difference of the two phases.
Our machinery products efficiently clear suspended solid, grease and oil from water. The combination of screening process and DAF result in BOD/COD removals upto 60%. We offer these machinery products under two heads. They are:

PWF Series
The PWF flotation system is based on the counter current flow principle through a plate pack. Compact, efficient & easy to maintain treatment systems have been developed based on innovative plate technology in combination with micro floatation. Very small air bubbles are released in the water making saperation of dispersed pollutants possible.

• Easy to expands to larger capacities.
• Competitive to other process.

Applications

• Mineral oil industry.
• Edible oil industry.
• Fish processing
• Mining industry.
• Offshore – onshore
• Petro-chemical industry.
• Pulp and paper industry.
• Textile industry.

In modern TPI Systems the separating surface area is increased vertically by adding a number of parallel plates mounted at an inclination. This not only affords a dramatic space saving but also facilitates very small separating diameter.
Features

• Our oil water separation unit consists of plate pack constructed of closely spaced corrugated plates which are inclined at a 45° angle or more.
• The waste water flows through these plated either parallel to the corrugations in "counter-current flow" or at right angles to the corrugations in "cross flow".
• Under laminar flow conditions, the short distance between the inclined plates is now the only distance over which the pollutants have to rise or sink before they are intercepted and separated from the mother fluid.

Our separation systems are used in various industry applications like:

• Mineral oil refineries, oil extraction, offshore platforms.
• Tank storage farms.
• Ballast water treatment.
• Petrochemicals.
• Galvanizing metal; mining industry.
• Edible oil refining.
• Foodstuffs industry.
• Paper & pulp industry.
