Warun Enterprises
Water Treatment Plants
With years of active presence, we are serving various industries by providing efficient systems for waste water treatment that result in saving energy. Our experts analyze client’s specific application requirements and then design and develop pollution control systems that suit their premises. Our broad spectrum of services and systems is as follows:


RIO Mixer

Submersible Mixers

We offer high performance systems for equalization/mixing of water such as submersible mixers. Our BRIO (high speed mixer for waste waters with moderate suspended solids) and RIO ( Low speed mixer for waste waters with high suspended solids such as in Bioreactors, Neutralization tanks etc.) provide very efficient mixing that ensures 75-85% energy saving in comparison with conventional units. The salient features of these mixers are;

• Thorough equalization is ensured by effective mixing in all directions.
• The mixers' MOC is compatible with pH range of 1-14.
• The solid sedimentation is prevented by the horizontal circulation of liquid currents
• The system is free from pores, nozzles and orifices. There is no clogging and recurrent clean up requirement as in case of bottom grids.
• Optimum flexibility is provided in the operation with the installation of multiple independent units.
• No pre-installation requirements like civil work/ structure etc.

Hence the units can be installed in an existing operation tank without emptying. Typically a single BRIO unit can provide effective mixing in 250m3 capacity rectangular tank. A single RIO unit is adequate for mixing 900-1000m3 volume. These mixers are effectively used operations / processes like equalization, degassing, neutralization, denitrification, activated sludge treatment plants etc.

Portable Solar Evaporation Pond

We offer portable solar evaporation pond which has portable ponds of 8m diameter with shallow depth enhancing evaporation rate. The portable pond is manufactured using high density PVC sheets, mounted on a mild steel or aluminum frame which can be folded whenever required. The cascade aerator improves the evaporation rate. This increases the contact between air and water by sucking and throwing large volume of liquid.

Compact Aerobic Treatment Systems

Owing to our vast industrial expertise, we offer compact aerobic treatment system based on state-of-the-art technology for bacterial treatment of industrial and domestic waste waters. In order to effect the highest oxygen transfer efficiency the system provides submersible aerators, which provide air bubble size as low as 10 microns. This provides maximum surface area and consequently high oxygen transfer efficiency at low energy consumption. Optimum surface area is made available by specially designed bio-media for ‘attached growth’ of bacteria in the system. Advanced diffusion technology enables to achieve high rate of energy efficiency. Assured biological treatment results are ensured by specially developed bacterial cultured with energy conservation between 40 to 50%. These improve solids separation, releasing volatile chemicals, and reducing sludge volume.

Lake Revival & Sustenance Systems

We offer high performance lake revival and sustenance systems for cleaning lake water and allied water bodies around golf courses, natural and artificial lakes at tourist spots. Oxygen is dissipated in every corner of the water body by an amalgamation of cascade aerators, submersible aerators and submersible mixers. Most of the time external bioremediation is not required. Our engineers specialize in offering system that reactivates inherent dormant biological system ensureing self-sustenance. Our range of revival systems includes following:

• Cascade Aerators that enhance the beauty of the lakes and at the same time provide oxygen & destratification
• Energy efficient submersible mixers that dissipate oxygen throughout the waterbody
• Submersible aspirator aerators provide required oxygenation

• Energy efficient
• Employ latest technology such as FAB, MBR etc
• Water recycle for Gardening, Cooling Tower, Toilet Flushing
• Compact with low foot print
• Low operation & maintenance costs
•Available in containerized (ready to use) & non containerized mode

Submersible Aerators

STORMIX in action:

Releasing micronised air in wide & deep zone:


STORMIX range of patented submersible aerators, provide very high oxygen transfer at low power consumption in waste water treatment applications.

The mechanical action of STORMIX overcomes the constraints of size reduction of air bubbles in diffused aeration. It sucks, micronises & releases atmospheric air in water to ensure equivalent oxygen transfer @40-50% lower power consumption as compared to conventional surface aerators, tank bottom aeration grids etc.
