How to Eliminate / Reduce Water Hammer in the piping System

Water Hammer or surge, It is big headache  to every Industry,Why and How it is happen? before that we should know What is this?

Any Liquid media /Water, which is passing into the pipe, all of sudden the flow restricts /Shut off of it by the valve across the flow, the back pressure will created due to return the media, [....]

How to Design Clarifier for Primary Treatment of Water Treatment Plant?

The Design of Clarifier mechanism is very important role in primary treatment of any water treatment plant.

The primary clarifier should remove both settleable organic and floatable solids (primary sedimentation or clarification) . Poor solids removal during this step of treatment may cause organic overloading of the biological treatment processes following primary treatment.

Normally, each primary clarification unit can be [....]

How to Remove BOD Using Mass Balance Method?

The amount of BOD removed by a treatment process is directly related to the quantity of solids the process will generate.

Key Note:

The actual amount of solids generated will vary with operational conditions and design, exact figures must be determined on a case-by-case basis;

however, research has produced general conversion rates for many of the common treatment processes. These [....]

Find Mass Balance of Your Settling Tanks

The simplest way to express the fundamental engineering principle of mass balance is to say,“Everything has to go somewhere.” More precisely, the law of conservation of mass
says that when chemical reactions take place, matter is neither created nor destroyed. This important concept allows us to track materials (that is, pollutants, microorganisms, chemicals, and other materials) from one place to [....]

Why Hypochlorite Consumption is higher than Chlorine?

In connection with previous post. let we see, why? hypochlorite consumption is always higher than that chlorine gas consumption.this is very simple calculation involves.

Generally the hypochlorite is hazardous than chlorine it is similar to strong bleach and available in two forms one is Dry HTH second as Liquid Sodium Hypochlorite.

In HTH forms the available chlorine normally about [....]

Sludge Drying Calculation in air drying

In water treatment plant, we need to be evaporated water or Reactivated sludge (MLSS) and Chemical sludge.In this case we should know the Heat energy calculation for Sludge drying.

It is help to analyze quondam of Heat Energy require to evaporate such a medium.

Ok, for example. we’ll take. A Sludge containing 80% water is to be dried at 100°C [....]
