Complete Plant Analysis Within Fingertips
At Urbanblue, we are passionate about wastewater and the science behind it. Our laboratory offers complete in-depth plant analysis to understand every aspect of treatment plant & increase the efficiency of existing assets. It also offers information on best practices to run the plant smoothly including but not limited to microbial culture dosing, chemical dosing, recirculation data & MLSS optimization.
List of tests that are included
Physical Parameters
Concentration range for most biological life is typically between 6 to 9. Acidic water is tough to degrade biologically.
It is one of the primary factors while evaluating wastewater. Fresh wastewater is usually light brownish grey in colour. Dark gray to black color represents septic conditions in wastewater. Color also depends on type of incoming effluent. E.g. textile industries.
Turbidity in wastewater is caused when small particles mix with the water stream and stay in suspension due to the motion of the water (colloids). Suspended particles in river water are for example soil, biological solids, or decaying organic matter.
Generally caused by presence of hydrogen sulfate. Bad odour can have psychological effects on people working nearby including Loss of appetite, nausea, and vomiting
The residue remaining after a wastewater sample has been evaporated & dried at a specified temperature.
Higher the salinity the less oxygen gets dissolved which may influence the bacteria at the biological treatment step.
Conductivity is essential for wastewater systems, as it tells you how many dissolved substances, chemicals, and minerals water contains.
Oxidation Reduction Potential is an indication of a solution's ability to oxidize or reduce another solution.
Chemical Parameters
COD test uses a strong chemical oxidizing agent (potassium dichromate or potassium permanganate) to chemically oxidize the organic material and possibly some inorganic materials in the sample of wastewater under conditions of heat and strong acid.
BOD test is performed by using a population of bacteria and other microorganisms to attempt to duplicate what would happen in a natural stream over a period of five days.
TKN is the sum of organic nitrogen and ammonia nitrogen. Most of the ammonia nitrogen in raw domestic wastewater (or any water in the neutral pH range) will be in the form of ammonium. Organic-Nitrogen in domestic wastewaters comes primarily from urea and proteinaceous matter.
Phosphorus is a naturally occurring nutrient found in soil and rocks that is required by all living organisms. In excess quantity and in combination with nitrogen results in algal bloom, which depletes DO present in aquatic system leading to death. It is removed either chemically or biologically.
Types of Sulphur present in wastewater systems are sulfate, reduced sulfide and hydrogen sulfide.
Chloride is a naturally occurring anion that is found in wastewater. It is often associated with salts such as potassium chloride and sodium chloride and is also known to be associated with total dissolved solids (TDS).
Harmful to many organisms presents in treatment process. Generally removed using either chelating agents or metal hydroxides precipitation
Creates lot of foam in treatment plant & can harm biomass negatively.
Biological Parameters
It is defined as the rate of BOD or biodegradable COD per unit volume of mixed liquor. A high F:M ratio means there is a greater quantity of food (measured as BOD, COD, or TOC) relative to the quantity of microorganisms available to consume that food. When the F:M ratio is high, the bacteria are active and multiply rapidly, but they are also more dispersed in suspended growth bioreactors. Because of that dispersion, a high F:M ratio creates an environment where the bacteria will not form a good, large, dense floc. For that reason, a high F:M ratio will often result in a poor settling sludge in the secondary clarifier and a turbid effluent.
Important for biodegradability of contaminants in plant.
RAS/WAS is required to maintain MLSS levels in plant
The Mean Cell Residence Time (MCRT) or solids retention time is an average measure of how long the microorganisms remain in contact with the substrate (food source). MCRT is also known as solids retention time (SRT).
Plant Status
Efficiency data about every plant asset to determine whether they are functioning properly
Hydraulic Retention Time is used to determine how long a water is going to stay in the plant.
Useful in determining clarifier efficiency and further enhancement of biomass.
The sludge volume index (SVI) is the volume in mL occupied by one gram of MLSS after 30 minutes of settling in a 1,000 mL graduated cylinder and has units of mL/g. The SVI is a measure of the settleability of the activated sludge in a secondary or final clarifier.
