Sludge Systems and Technology

Sludge Systems

Musol is a global supplier of innovative and effective odour control technology for municipal and industrial wastewater markets. The business will continue to be operated ethically, providing products and services that give value for money.

MuSol were the first company to pioneer the direct injection of a stabilized oxidizing agent into sludge systems where odour generation is a major problem. Often the thickening and dewatering of primary and secondary sludge give rise to offensive odours which, if not treated, can cause environmental nuisance and health and safety concerns for the public and site operators alike.

The MuSol MPOX range of products is engineered to be specific to the type of odour generated from particular dewatering operations.

Technology

When MuSol was first established, it was decided to go back to fundamentals and redesign the way odours were treated. Essentially, the foulest odours associated with sewage treatment processes are the result of chronic sulphate reducing bacteria. In order to avoid large odour extraction systems, MuSol have developed a method of eliminating the gas before it has the opportunity to escape into the air.

The technology uses a proprietary oxidizing agent that scavenges hydrogen sulphide and other reduced sulphides such as dimethyl sulphide and mercaptans. It does not react with any other organic compounds and therefore has a very low demand.

Chemicals that are typically used to treat hydrogen sulphide and other odour forming compounds are not specific and tend to destroy the organic material that is so important to the wastewater treatment process.

MuSol products oxidize sulphides converting them to sulphates. The products will react with either sulphides that are resident in the sludge or as soon as they are formed. A stabilizing product is added to prevent further emission of odours from the sludge during storage, transportation, disposal and long residence time in the sewer systems. MuSol products have been proven to be more effective that other odour control systems such as potassium permanganate, nitrate technology and ferric chloride.

Sludge, Septic Transport and Septicity Control

Sludge and Septic Transport

Recent changes to the way the public perceive odour has led to the necessity for plant operators and road hauliers to treat bad odours from their trucks. Odour coming from trucks on public roads can give rise to a large number of complaints, more often than not targeted at the sewage works receiving the sludge or septic water. MuSol have developed the perfect solution. A simple treatment system is retrofitted to the existing filling or emptying point to provide total deodorization of the tanker contents. In this way the operator can decide to treat at uplift or discharge in order to minimize the potential for odour complaints.

The product works so quickly that as soon as the active ingredient mixes with the odour it is neutralized, thereby avoiding the possibility of nuisance smells. The system, like all MuSol installations, is low capital cost and benefits from low running costs.

Septicity Control

The formation of hydrogen sulphide and other reduced sulphides is a significant problem for collection systems the world over. Typically gas formation leads to problems of odour, corrosion of capital assets and inlet toxicity to treatment plants. The MuSol MPOX-A system has been developed specifically to deal with the problems of inlet septicity and has been proven in both gravity and forced main systems.

Unlike other treatment systems where broad spectrum oxidizers may be used, the MuSol system is stabilized to give significant benefits of treatment downstream. This effectively protects capital asset further and for longer. Septicity is treated as it is generated by the unique way in which MPOX-A forms a chemical reservoir in the main. In head to head trials, MuSol MPOX-A has outperformed the competition in terms of cost and effectiveness - the next generation of septicity control has finally arrived.

Pathogen Kill, Cake Stabilization and Service Support

Pathogen Kill and Cake Stabilization

All over the world beneficial reuse of biosolids is regarded as a sustainable environmental option. Currently pathogen count is controlled by either digestion techniques or the addition of lime.

The equipment required for the application of lime is large and expensive and the addition program can be onerous for operators, not to mention the problems of ammonia odours and heat generation.

In contrast, MuSol MPSX has been developed to provide a fast acting pathogen kill system with low capital cost and no noxious odour generated.

The system consists of a liquid pre-treatment and a solid post-treatment. The result is controllable pathogen kill, where the user can select the degree of treatment.

The addition of the solid post-treatment allows the sludge product to be tailored for different applications, effectively making the sludge solids as small or as large as needed to achieve site requirements for storage and spreading.
