Are Your Pumps Running As Efficiently As Practical?
Are Your Pumps Running As Efficiently As Practical?

In water and wastewater operations, optimizing energy use plays a huge role in cost efficiency, but how can you know if pumping equipment and other motors are running as efficiently as possible? Analytics systems that interpret performance from a variety of data points — pump curves, run time, flow rates, vibration, temperature, energy consumption, etc. — can quantify pump operation to keep performance efficiency on an upward track.

DRINKING WATER TREATMENT CASE STUDIES AND WHITE PAPERS

  • Case Study: Chemplast Chooses Aquatech’s HERO™ & ZLD The Chemplast Mettur plant uses the Cauvery River as their main fresh water source. A strong industrial growth in recent years has resulted in water scarcity in the region. Industries are also required to follow strict environmental norms for discharging effluents. The intent of a Waste Water Treatment Plant was to have complete treatment, recycle and reuse of the combined waste water streams to reduce intake from the Cauvery River while not discharging any liquid waste streams.

ABOUT DRINKING WATER TREATMENT

Drinking Water Treatment involves the removal of pathogens and other contaminants from source water in order to make it safe for humans to consume. Treatment of public drinking water is mandated by the Environmental Protection Agency (EPA) in the U.S. Common examples of contaminants that need to be treated and removed from water before it is considered potable are microorganisms, disinfectants, disinfection byproducts, inorganic chemicals, organic chemicals and radionuclides.

There are a variety of technologies and processes that can be used to decontaminate or treat water in a drinking water treatment plant before the clean water is pumped into the water distribution system for consumption.

The first stage in treating drinking water is often called pretreatment and involves screens to remove large debris and objects from the water supply. Aeration can also be used in the pretreatment phase. By mixing air and water, unwanted gases and minerals are removed and the water improves in color, taste and odor.

The second stage in the drinking water treatment process involves coagulation and flocculation. A coagulating agent is added to the water which causes suspended particles to stick together into clumps of material called floc. In sedimentation basins, the heavier floc separates from the water supply and sinks to form sludge, allowing the less turbid water to continue through the process.

During the filtration stage, smaller particles not removed by flocculation are removed from the treated water by running the water through a series of filters. Filter media can include sand, granulated carbon or manufactured membranes. Filtration using reverse osmosis membranes is a critical component of removing salt particles where desalination is being used to treat brackish water or seawater into drinking water.

Following filtration, the water is disinfected to kill or disable any microbes or viruses that could make the consumer sick. The most traditional disinfection method for treating drinking water uses chlorine or chloramines. However, new drinking water disinfection methods are constantly coming to market. Two disinfection methods that have been gaining traction use ozone and ultra-violet (UV) light to disinfect the water supply.
