KWS Evaporators Private Limited Nolambur, Chennai, Tamil Nadu

In multiple-effect evaporators the heating medium in any subsequent effect is the vapor generated in the previous effect and thereby achieves a great steam economy. The purpose of TVR in a multiple effect evaporator is to compress the product vapor from an effect, to a higher temperature level by means of a steam ejector (TVR) to use it as the heating medium in that effect itself thereby reducing the prime steam consumption.

In Multi-Effect Distillation Evaporators, the upper end of the rising film evaporation tubes protrude from the upper tube plate of the calandria, so that the liquid after evaporation does not flow back into the tube and the vapor produced inside the tubes can leave the tubes without passing the liquid level on the upper tube plate. This avoids the excessive entrainment of the liquid and higher vapor and distillate salinity.

The pusher centrifuge is a continuously operating filtration equipment. It consists of two rotating baskets as outer basket and inner basket and which are fitted with axially slotted sieves. Both the baskets together rotate at very high speed in order to induce desired centrifugal force. The inner stage basket reciprocates axially inside the outer basket while both are rotating at same speed.

In falling film evaporator, water is distributed in tubes like a fine film layer on surface of tubes. Due to less wetting in surface and scaling, fouling materials will form a layer of insoluble scale that reduce its evaporation capacity. Feed vapour is separated in vapour separator. Use of falling film evaporator with multiple effects ensures high energy efficiency & is ideal for concentration of heat sensitive products, with low scaling tendency. We installed many falling film evaporator at various capacity for various industries. Mainly falling film evaporator are suitable for handling reverse osmosis reject water and having more than 40,000mgl TDS. This system evaporates up to 90% of feed and gives concentrate 300gram per litre. This concentrate is dried in drier crystallized in crystallizer or handled with forced circulation with KWS pusher centrifuge.

Evaporator plant one of the most experienced manufacturers of falling film evaporators in India for dairy, food processing, textile and chemical industries. KWS has developed energy efficient evaporators indigenously.The plants designed and commissioned by us are doing very well. We are committed to do better service by providing tailor made solutions for your effluent treatment needs.

We offer a wide range of continuous pusher centrifuges that are used to de water concentrated slurry of free draining particles. The Pushers offer high throughput in a continuous fashion. It is essential equipment meant for the separation of solids from liquids. However, the average particle size of the solids must be at least 0.1mm.Low moisture and high purity in discharged cake has made the pusher centrifuge an excellent choice for the separation purpose.
