Microbe-impregnated matrices reduce biosolids in wastewater

By Scott Jenkins |

High-surface-area beads filled with microbes are being used to reduce biosolids in wastewater. In one case, Drylet LLC (San Francisco, Calif.; www.drylet.com) has developed engineered porous particles that provide large surface areas (the equivalent of 12 football fields of surface area per pound of material). Using a proprietary process, the chemically inert particles are loaded with microbes that consume biosolids (sludge) in wastewater applications. The large surface area allows for the remarkably large microbe concentration of 1 × 1011 colony-forming units (cfu) per gram, or about 100 times the concentration of liquid products. The non-genetically modified microbes convert solid sludge mass into gases and water, reducing sludge volumes by up to 50% with no capital investment, according to the company. “We are looking to reprogram the microbial communities at wastewater treatment plants to promote the microbial activity of beneficial microbes and help them outcompete those that are less useful,” explains Luka Erceg, president and CEO of Drylet. Microbes within the porous network are protected from attack by other bacteria and protists in the water and can grow quickly. In addition, the process of introducing the microbes…

    First of all biosolids are made from sewage sludge which is made from cleaning industrial, medical storm and household sewage or waste water.
    Even though the extremely intelligent Drylet LLC engineers claim they can reduce biosolids with their process what they do not tell you is that they CAN NOT reduce extremely dangerous CANCER causing chemicals in the same stuff and there are countless numbers of them that the public is being exposed too.
    Here the rub which the US EPA, State EPA and the sewage industry and companies like Drylet call contaminates. Testing for just 8 chemicals in one spot cost and estimated $10,000.00 depending on the chemical being tested for.
    The United State Environmental Protection Agency (EPA) on the one hand pushes sewage sludge (biosolids) as fertilizer because of their collusion with large municipalities and the multi-billion dollar sewage industry and on the other hand EPA data, which is very hard to look up, makes sewage sludge (biosolids) one of the most dangerous contaminates of the 20th and 21st century.
    As follows:
    **Biosolids are derived from industrial, medical, storm and household sewage from large municipalities.
    **US EPA 40 CFR 261.30(d) and 261.33 (4): (Every US industry connected to a sewer can discharge any amount of hazardous and acute hazardous waste into sewage treatment plants.) There are over 80,000 chemicals in commerce and growing even today. It ends up in biosolids which is broadcasted over forest, farms and even bags taken to the consumer’s home and used in their garden
    **US EPA Office Inspector General (OIG) Report # 14-P-0363 in 09/2014 / Google and read it for yourself. To sum up, industrial pre-treatment is not working and has never worked and nothing has been done about it. It ends up in biosolids and sewage plant effluent. “The priority pollutants list has not been updated since 1981”
    **So when you hear anyone from the multi-billion dollar sewage industry or anyone with monetary ties to any part of the sewage industry say the chemicals in biosolids are minimal and inconsequential or that they support composting with biosolids, ask them for any test showing the degree of hazard and concentrations of 80,000 chemicals that are found in biosolids or a composted biosolids like Milorganite from Milwaukee.
    **Chemicals that are persistent in the environment, bio-accumulate in people and/or wildlife, and are toxic are called PBTs and neurotoxins such as microcystin (a hemotoxin), phycotoxins, domoic acid, brevetoxin. Because of these features, as long as they remain in commerce and may therefore be released into the environment, they will threaten the health of humans, wildlife including aquatic life.
    **Did I mention sewage sludge or biosolids spread on farms is loaded with unregulated phosphates? The main ingredient in proliferating algae.
    Now add pathogens and parasites which the sewage process, anaerobic digestion, exclaims gets rid of most of the bacterial contamination. Did I say most? What about the rest?
    You may ask yourself why the US EPA doesn’t say anything? Because they are part of the conspiracy. The US EPA does not require full disclosure of the above facts because, if they did, no one or very few would contaminate their property thus causing a collapse of the sewage industry and thousands of consumer fraud law suites.

    Now tell me your Environmental agencies are spending the money it would take to protect you from the sewage industry at a rate of $10,000.00 per every 8 chemicals per site with over 80,000 chemicals found in commerce today and growing.
    The answer is simple. No they are NOT and the US EPA and Congress allow this contamination to be broadcasted over farms and forests in the name of beneficial and “safe” which in my dictionary means FREE FROM RISK! It really boils down to, it cost more to put it where it belongs in a land fill as opposed to dumping it on some uninformed farmer or land owner.
    Biosolids are not SAFE!
    Food for Thought!
