Products

Following are the various range of products we supply and install

• Barscreen
  Bar screen remove objects such as rags, wipes and plastics, from wastewater and protect pumps from clogging. It is the primary level of filtration in wastewater treatment plants.
• Grit/Oil screen
  Mechanically Cleaned Bar Screen Designed to remove large solids, rags, and debris. Opening size: 6 to 38 mm (0.25 to 1.5 in).
• Corrugated Plate Interceptor (CPI) for oil separation
  CPI are used in separation of free oil & suspended solids from produced or oily wastewater. It works on basic principle of difference in gravity between the phases (liquid- liquid or solid - liquid).
• Effluent transfer pumps
  Centrifugal type or positive displacement type pumps used to transfer the sewage/effluent continuously to ensure non pulsing flow into the system.
• Effluent transfer pumps
  Centrifugal type or positive displacement type pumps used to transfer the sewage/effluent continuously to ensure non pulsing flow into the system.
• Filter press pumps
  Filter press pump is a centrifugal type with semi-open, nonclogging impeller pump with single row deep grooved heavy duty ball bearing with oil lubrication
• Chemical dosing systems
  Chemical dosing is the adding of chemicals into water/fluid or sludge to achieve required conditioning. This would make the treatment effective by various mechanisms such as charge neutralisation, settling of solids etc. System includes a dosing pump and chemical container
• Fine bubble air diffusers
  They diffuses tiny bubbles of gas into a liquid or a different gas. Typically, they diffuse bubbles of oxygen into liquids that need to be aerated, so they are similar in principle to wastewater aeration. Aerators work like a sieve or strainer to make air bubbles in a liquid
• Coarse bubble air diffusers
  Coarse bubble diffusers are used to aerate and or mix wastewater for sewage treatment. produce fewer, larger bubbles that travel faster than those produced by fine bubble diffusers.
• Blowers for aeration
  In the aeration basin microorganisms (sludge), a food source (pollutants in the wastewater flow), and oxygen are brought together. This results in controlled metabolism of the pollutants. The oxygen is typically supplied by blowers and the air is bubbled into the bottom of the basin.
• Clarifiers
  They are settling tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and (or) thickening.
• Flash mixers
  Rapidly and uniformly dispersing Coagulant all over the tank liquid. Usually slow to medium speed impellors are designed for optimum power consumption for maintaining turbulent stage of liquid.
• Flocculators
  Flocculators are used for waste or surface water clarification, to optimize particles coagulation and flocculation, prior to settler or DAF. Flocculation can be done in a plug-flow flocculator or in a tank reactor.
• Pressure Sand Filters
  PSF is a vertical vessel consisting of filling media, pipes and valves. The filling media consists of pebbles of different sizes, crushed gravels and sand for the pressure sand filter. Water passes through the various layers of the sand. Sediments, turbidity and organics are trapped and the water at the outlet is free from the above impurities.
• Activated Carbon Filters
  This will bring down the BOD level considerably and improves colour and odour. The filling media consists of a bed of activated carbon to remove contaminants and impurities, using chemical adsorption. Each particle/granule of carbon provides a large surface area/pore structure, allowing contaminants the maximum possible exposure to the active sites within the filter media.
• Iron removal systems
  A sub-micron rated sediment filter is capable of removing the iron precipitate that has emerged from the water. When water passes through the bed, the media attracts soluble ferrous iron and converts it to an insoluble state. That allows a filter to capture the iron precipitate, leaving the water iron-free.
• Filter press
  A filter press is used in liquid-solid separation. Specifically, the filter press separates the liquids and solids using pressure filtration, wherein a slurry is pumped into the filter press and is dewatered under pressure.
• Sludge drying bed
  Sludge-drying beds provide the simplest method of dewatering. A digested sludge slurry is spread on an open bed of sand and allowed to remain until dry. Drying takes place by a combination of evaporation and gravity drainage through the sand.
• Softeners
  Softeners are ion exchange units that remove calcium, magnesium, and other minerals from drinking water. Resin beads inside the softener trap the calcium and magnesium and exchange them for sodium or potassium.
• Reverse Osmosis Plants
  A reverse osmosis plant is a manufacturing plant where the process of reverse osmosis takes place. Reverse osmosis is a common process to purify or desalinate contaminated water by forcing water through a membrane.

Process Options

We carry out the designing, supply and commissioning of water purification plants and implementation of the following waste water treatment technologies.

• MBBR (Moving Bed Biofilm Reactor)
  The MBBR process utilizes floating High-Capacity Microorganism Biochips media within the aeration and anoxic tanks. The microorganisms consume organic material. It is a highly effective biological treatment process based on a combination of conventional activated sludge process and biofilm media.
• ASP (Activated Sludge Process)
  The activated sludge process is a multi-chamber reactor unit that uses highly concentrated microorganisms to degrade organics and remove nutrients from wastewater, producing quality effluent. The goal is to maintain aerobic conditions with the aid of a blower and to keep the activated sludge suspended.
• Extended Aeration process
  The extended aeration process purifies the wastewater by consumption of the organic compounds using air to oxidize the volatile material (both solid & liquid) into inert gases, water & sludge. By continued aeration of these concentrated solids, biological organisms are produced and grow in colonies.
• Anaerobic process
  Anaerobic digestion is a process through which bacteria break down organic matter such as animal manure, wastewater biosolids, and food wastes in the absence of oxygen.
