Coagulant Jar testing on your wastewater is a useful method in determining the correct product to fit your company needs. By jar testing on a sample of wastewater generated from your production line, significant benefits emerge such as product compatibility and validation, correct chemical dose and injection rate, and projected use-cost. Below we lay out…
Overview of sludge characteristics Sludge characteristics depend on both the original feedwater quality and the type of the unit operation from which the sludge is discharged. For conventional municipal wastewater treatment, the two main sludge streams are: from the primary sedimentation stage, producing primary sludge, and the secondary biological treatment stage, producing waste activated sludge (WAS) if the biological…
Wastewater treatment is a procedure of removing all the pollutants in the form oforganic matter and cleaning domestic water and sewage. Water is treated with the purpose ofreusing the water either by humans or animals or for any other purposes. Water discharged from houses. factories. orindustries is made to enter sewers.Waterfrom rains enters stormwater sewers. Water…
WHAT IS DISSOLVED AIR FLOTATION WATER TREATMENT? Dissolved air flotation (DAF) is a water treatment process designed to remove oils, solids, and greases. In fact, the process helps clarify wastewaters – and other waters – by eliminating different types of suspended matter. The DAF process dissolves air in the water under pressure – then releases it…
A great way to deal with algae, fat, oil and grease (FOG) is to install a Dissolved Air Flotation (DAF). However, many face difficulties in operating the device and therefore, plant fails. This article highlights some insights about DAF, how to select a proper DAF and what to do in order to have a good commissioning….
No one cares about wastewater until it is a problem. Say, the city is charging high surcharges or limiting permit levels that are impacting production or expansion plans. So, what do you do when there is a problem? Start with your goals The first step is to understand what is in the wastewater, how concentrated it is,…
Wastewater generated from food production and agricultural activities is a major source of environmental pollution. It is also among the most difficult and costly waste to manage because food processing wastewater can contain large quantities of nutrients, organic carbon, nitrogenous organics, inorganics, suspended and dissolved solids, and it has high biochemical and chemical oxygen demands….
Wastewater management is an undesirable task for facility managers and their staff. But, it’s an important job, because wastewater problems can quickly turn into a very expensive and unsanitary mess. Below is advice from our engineers about the ten most common wastewater treatment problems you may encounter at your facility and how you can fix them. Problem…
Using coagulants and flocculants to remove suspended solids during industrial wastewater or influent surface water source treatment is common practice. However, failure to properly store or manage these chemicals can lead to downtime, impact production, increased costs, decreased equipment reliability and shortened lifespan, on-site safety issues and more. For instance, poor water quality entering a process…
We classify wastewater treatment as a water use because it is so closely linked to other water uses. Before being released into the environment, much of the water absorbed by houses, industries, and companies should be treated. If you’re unsure what “wastewater treatment” means, think of it as “sewage treatment.” Nature can deal with small amounts…
