Suspended solids SS

Points of Chemical Addition In independent physical-chemical treatment or in phosphate removal in the primary clarifier ahead of biological treatment, chemicals are added to raw sewage. In tertiary treatment for phosphate removal and suspended solids (SS) reduction, they are added to secondary effluent. In both cases, proper mixing and flocculation units are needed. For phosphate removal or improvement of SS capmre in biological secondary treatment, chemicals are often added directly to aeration units or prior to secondary settling units, without separate mixing and flocculation. In some phosphate removal applications coagulants are added at... 

Suspended solids (SS) present in the BW contribute to erosion-corrosion of the electrodes and counter-electrodes. Additionally, the presence of SS in the BW increases the potential for foaming and ground fault arcing. 

If the water sample has high turbidity, it may be necessary to separate suspended solid (SS) from water before the analysis as described later. Chemicals that are hydrophobic and of low water solubility are easy to adsorb on SS. 

In a country with severe water scarcity, the government has placed limits on the amount of fresh water that may be used by industry. A company has three main water-using operations. In each operation, the water picks up contamination in the form of suspended solids (SS). The existing concentrations of SS are given in Table 26.19. 

Finally, it is worth mentioning the turbidity of the water, which reflects the presence of suspended solids (SS), such as dust and sand particles as well as organic matter and colloidal particles. Most water sources supplied from a well or a city main will have low levels of suspended solids, perhaps... 

Sand media will usually provide efficient suspended solids (SS) removal for suspended matter above 30 g particle size. 

Cooling systems are dynamic and therefore need various control and monitoring systems. Among them are systems for injection of acid or specialty chemicals, real-time monitoring and recording of the water treatment program performance, and the control of pH, TDS, oxidation reduction potential (ORP), suspended solids (SS), etc.

Example 2.3 A snspended solids analysis is run on a sample. The tared mass of the crucible and filter is 55.3520 g. A sample of 260 mL is then filtered and the residue dried to constant mass at 103°C. If the constant mass of the crucible, filter, and the residue is 55.3890 g, what is the suspended solids (SS) content of the sample ... 

The data in Table 5 for the 5-wk period of June 28 to August 1, 1975, indicate an average 33% reduction in suspended solids (SS) from 5.4 mg/L down to 3.6 mg/L was achieved across the unit. 

Suspended Solid (SS) A measure of solids that are suspended (not dissolved) in the wastewater. Suspended solids will lower the amount of light and oxygen in a body of wastewater. Over time, suspended solids will settle from the wastewater, blanketing the floor with a layer of sediment called sludge. 

A 10 gal/day (l.OMGD) wastewater from a treatment plant contains 0.2mg suspended solids (SS) per cubic meter of wastewater. The separated sludge from the plant consists of the SS. If 10% by weight of lime is required to stabilize the sludge treatment and 80% of the solids are captured, calculate the daily and annual lime requirements. 

Assume the suspended solids (SS) are related to the volume rate of flow of water (q) through the relationship ...

Although there are 30 water quality parameters available, only 23 completely monitored parameters were selected. A total of 254 samples were used for the analysis. The 23 water quality parameters were dissolved oxygen (DO), biological oxygen demand (BOD), electrical conductivity (EC), chemical oxygen demand (COD), ammoniacal nitrogen (AN), pH, suspended solids (SS), temperature (T), salinity (Sal), turbidity (Tur), dissolved solid (DS), total solid (TS), nitrate (NO ), chlorine (Cl), phosphate (PO ), zinc (Zn), calcium (Ca), iron (Fe), potassium (K), magnesium (Mg), sodium (Na), E.coli and coUform.
