Several studies have shown that chlorination will kill algae. The focus of most of these studies has been on the impact that algae have on the chlorine demand of plant effluents.
In these studies, the chlorine doses used have been large ( mg/L) and the contact periods short (15 min to 2h), conditions under which algae are killed and lyse.

Unchlorinated domestic sewage was found to be a relatively weak inhibitor of external fertilization in 3 marine invertebrates. Chlorinated sewage was a potent spermicide, active in inhibiting fertilization in concentrations of available chlorine as low as ppm. Sodium hypochlorite in seawater duplicated the effect, and excess sodium thiosulfate terminated it.
The possibility of chlorine Cited by: Prechlorination is used to control odor, which is mostly associated with hydrogen sulfide in the influent wastewater. Effects of selected wastewater chlorination products and captan on marine algae book Intermediate chlorination is used to control the undesirable growth of filamentous microorganisms, by applying chlorine to return sludge.
Chlorine can also be used to control algae growth on clarifier weirs and wastewater wrcch2016.com: Arumugam Sathasivan, Bhagya S Herath, Lalantha Senevirathna, George Kastl. May 03, · Thus, anaerobic digestion is likely to be the near-term, appropriate use of algae biomass at wastewater treatment plants.
However, algae typically yield less methane than wastewater sludge (∼ vs. L CH4/g volatile solids introduced). Ammonia toxicity and recalcitrant cell walls are commonly cited causes of the lower wrcch2016.com by: Chlorine, the most widely used disinfectant for municipal wastewater, destroys target organisms by oxidation of cellular material.
It may be applied as chlorine gas, hypochlo- rite solutions, and other chlorine compounds in solid or liquid form. Like chlorine, ozone is a strong oxidizing agent. Thus, anaerobic digestion is likely to be the near-term, appropriate use of algae biomass at wastewater treatment plants.
However, algae typically yield less methane than wastewater sludge (∼ vs. L CH4/g volatile solids introduced). Ammonia toxicity and recalcitrant cell walls are commonly cited causes of the lower wrcch2016.com by: Apr 02, · In one of the first studies to examine the potential for using municipal wastewater as a feedstock for algae-based biofuels, scientists found they could grow high-value strains of oil-rich algae while simultaneously removing more than 90 percent of nitrates and more than 50 percent of phosphorous from wastewater.
Effects of operating conditions on THMs and HAAs formation during wastewater chlorination Article in Journal of hazardous materials () · April with Reads How we measure 'reads'. Triclosan (TCS) is an antimicrobial compound being increasingly used in personal care products (PCPs) over the last 40years, and as a result is present in wastewater treatment plant (WWTP) effluents.
Kolkwitz listed 61 diatoms, 42 green algae, 41 pigmented flagellates, 23 blue-green algae, and 5 red algae as organisms of oligosaprobic and /or unpolluted zones and Lackey found 77 species of planktonic algae in the clean water portion of a small stream, 40 of which were absent in the polluted area[15,16].Cited by: The data base covers hazards and consequences related to onsite use and transportation of the disinfectants and ultimate disposal of disinfected effluents.
A major segment of the data base deals with the effects of chlorination products in aquatic ecosystems. Chlorine Shock Treatment For Slime and Algae Control CAPITAL CONTROLS Slime, algae and other forms of aquatic life, if allowed to grow and thrive unchecked can greatly reduce the efficiency of watercooling systems.
Over the years, control of these growths has been successfully accomplished by chlorination. Under certain circumstances the continuous. However, the pre-chlorination treatment for raw water has been proved to increase the dissolved organic carbon concentration due to the lysis of algae cells and disinfection by-products formation.
The impact of water treatment processes on disinfection by-products formation remains complex and variable, as demonstrated by recent literature. This situation continues to persist; most of the present marine research, to be discussed later, is oriented to the intermittent effects of power plant chlorination or is conducted under laboratory conditions with clean dilution water rather than with chlorinated wastewater effluent itself.

Sep 06, · ALGAE AND WATER POLLUTION However, certain algae grown up in water polluted with organic wastes play an important part in “self-purification of water bodies”.
Some pollution algae may be toxic to fish, human and animals using polluted water. In fact, algae can play significant part of food chain of aquatic life, thus whatever alters the. The effects of air and vacuum pockets present in a liquid piping system can negatively impact not only pump, meter, and control valve operation but can also be responsible for pipeline breaks and collapses.
Choosing and installing the correct air valve is critical to all liquid piping systems. This manual provides essential information for.
Reclaimed or recycled water (also called wastewater reuse or water reclamation) is the process of converting wastewater into water that can be reused for other purposes. Reuse may include irrigation of gardens and agricultural fields or replenishing surface water and groundwater (i.e., groundwater recharge).Reused water may also be directed toward fulfilling certain needs in residences (e.g.
Algae have also been deployed for low cost and environmentally friendly wastewater treatment [49–51].
