Renewable Natural Gas (RNG) – also called biogas – is an increasingly important, environmentally responsible and renewable (as its name implies) source of energy that results from decomposition of organic matter in anaerobic conditions. This organic matter comes from various sources, including farm animal waste products (e.g., manure).

Water is a component of converting organic waste into biogas. Spiral Water filters can effectively filter this water from wastewater stream, which can be further treated before disposal, and concentrate the solids, which can then be converted to fertilizer and sold.

Spiral Water systems also condition and optimize volatile TSS VSS particle size in feedstocks to anaerobic digesters, resulting in higher production of biogas per a given volume. Placed before an anaerobic digester, our filters also concentrate and remove nondigestible solids. They also condition volatile solids before they enter the anaerobic digester. When solids go through the carefully selected micron-size screen, anaerobic digesters are shown to create 10-30 percent more methane in the same footprint in a shorter digestion cycle time.

Another benefit is that because our filters clean mechanically, they also remove nondigestibles from the wastewater stream. By keeping the anaerobic digester tanks cleaner, our filters help to reduce operational expenses.

Vertical farming has the potential to revolutionize the way food is produced and reduce the environmental impact of agriculture. It allows for year-round crop production in urban areas, requires a much smaller land footprint, consumes far less water than traditional agriculture, and also provides a way to grow fresh produce closer to the point of consumption.

Spiral Water filters provide a key component in any water recovery and reuse approach, and are very well-suited to the requirements of vertical farming. Nutrient-rich water used in hydroponic drips can pick up particles and other solid debris during this process. Spiral Water filters can ensure that water is free of these contaminants before being reintroduced into the system so that it does not foul nozzles or disturb the lines. Our filters can also be used to treat wastewater bound for discharge and ensure that it complies with strict community discharge limits.

Our systems set the standard for liquid filtration in industrial wastewater streams. Our products can remove 50% or more of particles sized 20 microns and larger. By filtering industrial wastewater, facilities can reuse that water for industrial processes—thereby reducing total water consumption—and make contamination disposal more efficient. Read more in this article that describes how our filters are used in both industrial and municipal applications.

Most desalination facilities, whether used for treatment of seawater or brackish water, rely on water filtration processes, from prefiltration to reverse osmosis (RO) systems, to produce clean and potable water suitable for various applications. The use of modular, containerized units has augmented the ability to leverage the power of desalination in locations where the construction of large-scale plants is unnecessary or cost-prohibitive. Either way, the utilization of water filtration technologies in land-based desalination enables the sustainable production of clean water resources, contributing to the provision of reliable and safe water supplies for industries and communities alike.

Oil and gas production requires large volumes of water. Facilities can turn to water filtration to lower their total water demand for processes like hydrocarbon extraction (both liquid and steam), cooling, well flooding, and having sufficient flowback water. Establishing water filtration solutions for wells and processing centers will continue to become more essential as demand for oil and gas increases.

While the amount of water needed to produce a barrel of oil varies, it is estimated that it can take 5 barrels of water to produce one barrel of oil. As oil wells age, more water is needed to extract the oil. Practices such as injecting water into oil fields via injection wells is a more sustainable solution than tapping into freshwater sources, but this water must be treated before being reused or disposed of.

Pharmaceutical manufacturing relies on Purified Water (PW), a regulated grade of filtered water that has lower levels of particles, bacteria, and cells than found in other grades of filtered water. Manufacturers use PW as an agent for cleaning, as water for injection or an ingredient, or as a solvent. Using PW for these sensitive processes makes the products much safer while simultaneously reducing cleaning and maintenance costs.
