Wastewater Treatment

SELECT-Protein^®: Essential in Dairy Waste
If you have a cheese plant with foaming or odours in the sludge storage tank, this is partly due to undigested casein. Bacteria can break down milk sugars easily, but milk solids, like the protein casein, are especially tough. Casein passing through will cause many issues in plants. SELECT-Protein® will quickly degrade and fix this, while also lowering COD levels and stopping odours.

SELECT-Protein^® is great to apply to the head of the plant. This is a quick fix if you have 10# of food quickly passing through a 5# box. This product has saved at least one cheese plant from expanding its wastewater treatment plant.

A Revolutionary Product for All Protein Waste
Undigested protein waste is an issue with many sections of the food processing industry. SELECT-Protein^® provides the tools bacteria need to digest any complex protein found in wastewater. Instead of turning into sludge in your storage tanks or lagoon, SELECT-Protein^® turns this waste into fuel for your beneficial bacteria.

What can SELECT-Sludge^® do for your digester?

The catalysts in SELECT-Sludge^® convert insoluble BOD into soluble simple sugars and materials that the bacteria can more easily digest. This process promotes sludge reduction in aerobic digesters.

When this biochemical catalyst is added into a wastewater treatment plant, digestor or sludge storage tank it degrades the grease, oils, waxes and papers that the bacteria cannot. This liberates difficult-to-access carbon and turns it into food for the bacteria, creating less sludge.

This improves settling, creates a denser sludge and gives you much less to transport and dispose of.

If you think filaments are causing poor settling, contact the Parklink Laboratories for a microscopic analysis.

– Improves settling
– Improves dewatering
– Reduces digester sludge volume
– Lowers polymer use
– Lowers sludge hauling

The Only Corn Syrup Degrader
Corn or Vegetable Processing (6) High Fructose Corn Syrup (HFCS), corn starch, and vegetable starch are among the most difficult complex carbohydrates to degrade in wastewater. These compounds are extremely high in BOD and their complexity resists bacterial breakdown.

Facilities with these constituents in their wastewater try to counteract the high COD by over-aerating. Over-aerating increases bad odours, costs thousands of dollars in electrical bills, and only provides a marginal reduction in COD.

A new biocatalyst to break down these complex, high molecular weight polysaccharides in wastewater processes. SELECT-Starch^® speeds up the degradation of HFCS and vegetable starches while allowing major savings on aeration and other operational costs.

When used for HFCS: Qwik-Zyme CS allows complete breakdown of HFCS into glucose to be further digested by bacteria. Its high-performing biocatalyst is an essential piece missing from HFCS wastewaters.

When used for corn and vegetable starches: SELECT-Starch^® is used to break down the complex starches into glucose and other bio-available simple sugars. Alternating between SELECT-Starch^® and SELECT-Protien^® when breaking down starches allows the bacteria to access even more of the simple sugars and degrade them.

Benefits:
– Fast degradation of High Fructose Corn Syrup
– Aids Bacterial Digestion
–  Reduces Odours
– Reduces Aeration Expenses
– Reduces Sludge Production
– Improves Dissolved Oxygen

Why is it so important to control fats, oils and grease?

In the winter months, when water temperatures are colder, the naturally occurring bacteria cannot completely break down FOG and the fatty acids that build up in the wastewater plant. These fatty acids are then taken up by filaments like Microthrix Parvicella and Nocardia which allows them to float and foam. SELECT-Grease^® breaks up these fatty acids and cuts off the filament’s food source.

SELECT-Grease^® works well with Select-Defoam-bac^® and is used in all types of municipal and industrial applications. Select-Defoam-bac^® alters the bacteria populations so the foam will not return while SELECT-Grease^® helps to get the grease under control.

This product is either metered or poured into the front end of the wastewater process.

Degrade It, Don’t Push It!

Most grease removal products are citric-based oil-separators that just push along the grease or don’t work at all. If pushed, the harmful materials go right to the wastewater treatment plant which can cause major upsets and foaming. SHIELD-Degrease^® will degrade and digest heavy buildup of fats, oils and grease stuck on the walls of pump stations and pipelines, leaving the wastewater free of incoming grease.

Flushable Wipes Clogging Lift Stations

Operators are fighting against the issues caused by “flushable” wipes all over the country. While marketed as biodegradable, the majority of these wipes are made from polyester, a material that generally takes 20 to 40 years to break down. Parklink has seen firsthand the clogs and compaction these wipes cause, binding together with grease and other matter in sewer lines and lift stations. The wipes really begin to cause problems when combined with grease to form mats and float, clogging lift stations. SHIELD-Degrease^® dramatically hydrolyzes grease to rob flushable wipes of the glue they need to form large clumps and keep operations running smoothly.

The Difficulty of Degrading Proteins Anaerobically
Anaerobic bacteria tend to be poorly specialized for the degradation of protein. Carbohydrates usually make better feed substrates than protein due to their high cBOD content and the low nitrogen requirements of anaerobic bacteria. Fat, oil, and grease—while usually undesirable in a digester—also have a high cBOD content. This means that anaerobic hydrolysis favours the degradation of fats and complex sugars, over the degradation of proteins. However, when broken down, protein provides valuable amino acids which improve the production of naturally occurring anaerobic enzymes. When free amino acids are absent, anaerobic bacteria need to produce them using simple carbon substrates and ammonia, a process that takes additional metabolic steps and wastes carbon, making the process inefficient.

ANAGEN-Protein^® improves anaerobic efficiency by outsourcing that extra metabolic step in the degradation of proteins so the anaerobic bacteria can focus their resources on breaking down carbon substrates and producing methane. This leads to improved methane generation, lowers effluent COD, and improved volatile solids destruction.
