Relationship Between TS, TSS and TDS

Relationship between TS,TSS and TDS

These three solids tests can be related with Equation :TS = TSS +TDS

Total Solids. For regulatory and treatment purposes, total solids (TS) can first be classified as
suspended or dissolved. Total solids, as defined by Standard Methods and EPA, is the material
residue left in a vessel after evaporation of a sample and [....]

Differentiate between settleable and floatable solids |Types of Solids

Types of Solids:

                      The most basic solids differentiation is between settleable and floatable solids. An additional important differentiation is between volatile and non-volatile solids. A chemical or biological solid can potentially be removed from a wastewater by conversion through biological or chemical activity or incineration if the solid is organic and volatile (burnable at around 550°C). A volatile [....]

Determination of Sulphite

Sulphite:

The Determination of sulfite usually is made only on boiler waters.Generally speaking sulfite is not present in natural water. in boiler feed water sodium sulphite is fed to remove dissolved oxygen.

Reagents

1. 1N Hydrochloric acid 1+1

2. Starch indicator solution

3. Standard potassium iodide-iodate solution.

 

Procedure:

Place 10ml of 1+1 HCL in a 250 ml flask. rapidly [....]

What is Solubility | Molarity

Solids, liquids, and gases may dissolve in water to form solutions. The amount of solute present may vary below certain limits, so-called solubility. The strength of a solution can be expressed in two ways:

(1) weight (lb) of active solute per 100 pounds (i.e. %) and

(2) weight of active solute per unit volume (gallons or liters) of water. [....]

What is Water Filtration?

Water filtration is a physical process of separating suspended and colloidal particles from waste by passing the water through a granular material. The process of filtration involves straining, settling, and adsorption. As floc passes into the filter, the spaces between the filter grains become clogged, reducing this opening and increasing removal. Some material is removed merely because it settles on [....]
