Waste to Energy By Wastewater Removal
Organic wastes can be valuable for companies as well, by digesting waste to energy including anaerobic treatment.
Waste streams from the industry including treatment of sludge from a wastewater treatment plant can be digested under anaerobic conditions. The created gas can be generated into energy and the heat can be used to keep your digester at the optimal temperature. The energy from your waste can either be used in your own factory or can be sold as green energy.
On water streams containing Nitrogen and Phosphorus you can grow algae. Algae can be used as ground source for biofuels, plastics and artificial products.
Concentrated oils and fats separated from your wastewater can be a source for energy or reused in rendering processes.
Phosphorus can be recovered by addition of specific chemical to create struvite, which can be used a fertilizer.
Your waste and wastewater has value and Nijhuis Water Technology can design systems to recover these valuables for you with waste to energy by wastewater removal.
Aecomix - Sludge & Waste Digestion
Nijhuis Water Technology supplies sludge & waste digesters, where under anaerobic circumstances your organic waste material is transferred into biogas, heat, energy and fertilizer. The feed into the process could consist of:
Depending on the raw materials, Nijhuis Water Technology will select the optimal system. This system can include the following steps: raw material preparation, balancing, mixing, digestion, biogas conditioning, biogas usage and digested sludge processing and digestate treatment.
Nijhuis Water Technology has a specialized division, Thecogas Biogas, who supplies manure & co digestion systems, where under anaerobic circumstances agriculture wastes are transferred into biogas, heat, energy and fertilizer. The feed into the process could consist of:
Depending on the raw materials Nijhuis Water Technology will select the optimal system.This system can include the following steps: raw material preparation, balancing, mixing, digestion, biogas conditioning, biogas usage and digested solids processing and digestate treatment.
Algae Refining & Harvesting
The use of algae in water treatment is for Nijhuis Water Technology an innovation as there is a general interest in growing and harvesting algae.
In water treatment the interest in algae is based on the fact that they consume nitrate, phosphorous and carbon dioxide and by growing and multiplying they produce oxygen. Nitrates and phosphates are often byproducts in effluents from, in particular anaerobic treatment plants.
Algae are actually responsible for a substantial share of the oxygen production by plants in the world. There are thousands of different species. Some species produce up to 50% of their bodyweight as (vegetable) oil, others are rich in protein. There are many known applications for algae like biofuel, plastic or artificial products.
Even based on conventional algae ponds, the production per ha of land can be over 10 times higher in terms of energy crop, compared to growing other crop like palm trees or soya.
