What is Anaerobic Digestion? Anaerobic Digestion is a natural biological process that can be used to generate renewable energy and manage waste. The process takes place in an oxygen-free digester, where micro-organisms convert organic material such as food waste, slurries and crop residues into: Biogas Biogas is a mixture of biomethane gas and carbon dioxide. The biogas can be used directly in CHP engines to produce renewable heat and power, or it can be burned to produce heat only. Alternatively, biomethane can be produced by removing the carbon dioxide from the biogas. The biomethane has many valuable uses. It can be injected into the gas grid as a renewable replacement for natural gas or it can be used as vehicle fuel. Digestate The by-product from the AD process is called ‘digestate’. It is rich in valuable plant nutrients such as nitrogen and potassium, and can be used as a renewable fertiliser/soil conditioner.

Colloide provides circular and rectangular scraping systems (plastic and steel) for settlement and flotation tanks. These tanks are generally rectangular or circular, designed to separate solids from the liquid by either settlement or flotation. Circular Tanks We offer two alternatives for circular tanks: -A rotating bridge structure powered by a peripheral drive unit. The bridge supports a frame below it onto which is fixed sludge scraping blades at floor level and a scum blade at top water level. -A fixed bridge mounted on the walls of the tank. A central drive unit rotates the scraping mechanism around the tank, the sludge scraping blades diverting the sludge to a hopper. Rectangular Tanks A chain and flight principle is used for rectangular tanks, consisting of two main chains which move the scraping booms up and down the tanks. When scraping at top water level, the booms push the floated material to one end of the tank, where it is collected by a rotating sludge pipe.

Colloide‘s Dynamic Sand Filter offers an excellent treatment system for the removal of solids and other contaminants from a water/wastewater stream. This filter is always on line, continually filtering the incoming water while continually backwashing a small portion of the sand bed. The Dynamic Sand Filter process: The feed water is fed into the filter at the base of the active sand bed through the distribution ring. It then flows upward through the downward moving sand bed where the solids are filtered out. The clean filtrate exits the filter through the overflow weir. The continuous reject flow of washing water is discharged through a separate outlet. The dirty sand is continuously removed from the active sand bed thanks to the action of the air-lift pump. This pump draws the contaminated sand from the bottom of the filter body. A mixture of sand, dirty particles and water is transported upward through the air-lift pipe into the washing chamber at the top of the filter.

District heating systems include a centralised energy centre which then distributes the heat through a network of insulated pipes to the buildings which are connected to the network. The network of pipework consists of a flow and return loop which passes each building. Colloide uses local substations in each building to control the flow of water from the district heating pipework loop through each substation and this flow is used to generate heat in the local building. The central energy centres are generally designed to have more than one energy source, which allows the plant operator to select the most cost efficient and sustainable way of providing the energy needed with the energy sources being brought on and off line to meet demand. We design and build the district heating and cooling networks to include the pumps, pipework, thermal stores, instrumentation, control systems, local substations, heat exchangers and communication through a central control system.

Colloide designs and installs heat pump systems. The heat pump extracts the energy at the source temperature and then raises the temperature to a useable level. A heat exchanger is used to extract the heat from the circuit at this point, with the now cooled medium being returned to the source where it is reheating. Reversible heat pumps can also be used in cooling function which can be important in the summer months. The heat pump works as part of a closed loop, operating between the heat source and the building where it is to be used. Heat sources include air, water, ground and waste heat. The higher the temperature and larger the size of the source energy, the better it is for providing energy. Colloide designs its systems to maximise the return from the heat source. Our heat pumps include a control system. The control system will vary depending on the plant, but is always designed to give our customers full control, including the ability to monitor performance remotely.

Colloide designs and builds customised energy centres which generate heat which can then be distributed to buildings or district heat networks. We can also incorporate CHP units within the energy centre, providing electricity along with heat and a low carbon heat and power solution. Our energy centres are often designed to have more than one energy source, allowing the plant operator to vary the energy sources in relation to the energy demand and the best value for money at a given time. The energy sources may include: Gas fired boilers. Biomass boilers. Heat pump. Oil fired boilers. Combined Heat and Power (CHP) unit Our centres are engineered to include the energy sources, thermal stores, instrumentation, control systems, pumping and pipework network – building in as much flexibility as possible so that the plant can be operated as efficiently as possible.

Clarifiers are settling tanks built for continuous removal of solids. Clarifiers are generally used to remove solid particulates or suspended solids from liquid for clarification and (or) thickening. We use lamella settlers within our clarifiers, which greatly increases the clarifier capacity and enables a much greater flow to be treated in the same footprint as conventional clarification. Our design also ensures maximum efficiency in terms of upward flow velocities. The lamella settlers can be used in new builds and are also an excellent option for upgrading and increasing the flow through an existing plant. Our clarifiers can be designed in a wide range of sizes and configurations to suit the individual needs of each of our clients. The clarifier can be used as a standalone system, taking the full plant flow, with or without additional equipment such as sand filters, screens, etc.
