DC37 MBBR Media: Best Choice for Municipal and Industrial Wastewater Tanks

A common problem for municipal and industrial wastewater plants is to treat a high amount of water in an efficient manner in a limited space and at a reasonable operating cost. This is what makes engineers and plant operators opt for Moving Bed Biofilm Reactor (MBBR) systems. The biofilm carrier media is the element at the core of these systems as it gives a surface for good bacteria to multiply and metabolize contaminants. In the wide variety of choices available, DC37 MBBR Biochip Media is one of the most popular choices due to its high surface area, sturdy construction and consistent performance. Used in either a city wastewater plant or a manufacturing plant, DC37 media helps to maintain stable treatment performance even in the face of changing operating conditions.

Features of DC37 MBBR

DC37 MBRRs media is a product that establishes a good breeding ground for beneficial microorganisms that scrub wastewater. At first glance it might seem straightforward, but every component of the design has a role to play. A variety of internal channels and protected areas in the MBBR Biofilm Carriers media provide bacteria with the opportunity to attach and create a stable biofilm. The protected areas minimize the chance of the biofilm from being carried away with water flow within the tank.One of the main features of DC37 MBBR media is its large specific surface area. The larger the surface area the more room the microorganisms have for growth and the higher the amount of pollutants that the treatment system can handle for the same tank size. This can be particularly beneficial for facilities that want to expand treatment capacity but can't afford to construct new tanks or expand their footprint.One of the other important features is that it is lightweight. The media is designed to stay in suspension in the water using aeration or mixing systems. Wastewater is treated by the bacteria as the water is moved through the tank from various angles, increasing the efficiency of treatment.DC37 media is also known for its durability. Wastewater treatment systems are in continuous use and frequently work in challenging environments. The carrier material is designed to endure friction due to repeated movement and impact within the reactor. This minimizes replacement rate and low maintenance.The media is very suitable for municipal and industrial wastewater use. For instance, a municipal waste-water treatment plant can use DC37 carriers to process waste-water with varying loads, and a food processing factory can use the same media to treat the waste-water from the factory with its high organic load. In both, the media is used as a stable surface to allow the growth of biofilm and ensure steady treatment.Since DC37 MBBR media has a good balance of surface area, strength and movement properties, it is used in new installations and retrofits for existing wastewater treatment systems.

Adaptation to Water Depth

The advantage of DC37 MBBR media is that it can be effective in tanks of varying water depths. Wastewater treatment plants are not typically constructed to the same standards. Many municipal plants are equipped with deep biological reactors, and many industrial plants are limited by space or existing infrastructure and are typically shallower. An operator can have greater flexibility in designing or upgrading a treatment system with a carrier media that can adjust to these conditions.With adequate aeration or mixing, the media should be free to move around inside the reactor, and this is what is going on with DC37 media. Rising air bubbles help to maintain the carriers in an even distribution throughout the water column in deeper tanks. This action keeps the biofilm constantly in contact with oxygen and food and promotes healthy bacteria. Wastewater is also continually exposed to the biofilm which aids in reducing the pollutants.Even in shallow tanks, good media flow can be provided by using the aeration system correctly. As the carriers keep moving and interacting with the wastewater, there is less chance of stagnant areas with lower treatment efficiency. This is beneficial to facilities that must fit into existing tank space and not build new treatment basins.An example of this is in plant expansion projects. Many older wastewater facilities were constructed years ago and do not have tanks that are the appropriate size for modern designs. Operators may simply upgrade the biological treatment process rather than replacing the reactors by adding MBBR media. The upgrades are more viable and cost-effective for DC37 carriers as they can adjust to the available water depth.When deciding what media to put in an MBBR system water depth needs to be carefully examined as will aeration and the tank design itself. Even so, DC37 media's steep operational curve allows its suitability in a wide range of applications making it adaptable for engineers to successfully complete water treatment systems at any tank depth including in municipal waste water treatment facilities, food processing waste or a multitude of other industrial applications.

Why DC37 Beats Other Carriers?

The selection of the correct MBBR carrier will directly affect the treatment performance, operating stability and long-term maintenance. Many types of carriers are on the market, but many people choose to use DC37 MBBR media due to its many desirable properties in one design.A factor that sets DC37 apart is its combination of surface area and durability. There are also carriers with a large surface area, but the structure would wear out over years of continuous use in the reactor. Others are very stable but do not offer enough surface for the growth of biofilm. To offer sufficient protected attachment sites for microorganisms and the strength of continuous operation, DC37 is designed to provide both.The internal structure of the carrier also provides protection against excessive shear forces to the biofilm. Constant mixing and aeration may sometimes cause removal of sections of the biofilm in wastewater treatment tanks. There are sheltered areas in DC37 that help facilitate the presence of beneficial bacteria and supply oxygen and nutrients at the same time. This will help to ensure a stable biological population even under a fluctuating flow regime.Another benefit is that it is versatile. Certain carrier designs work best within a given set of operational conditions. DC37 is suited to a variety of municipal and industrial wastewater applications and can be used for various treatment objectives. The media can be used in biological treatment of domestic sewage, food processing wastewater, beverage industry wastewater and wastewater from light manufacturing industries.Operators value a carrier that's predictable when it's time to upgrade their facility. Perhaps they're seeing more wastewater than they expected and the most economical solution is to add more DC37 media to existing basins rather than building a whole new plant to meet demand. By simply adjusting the fill ratio for the media in the DC37 based units, they can potentially increase capacity and maximize their use of existing plant structure. Cost will ultimately play a role in carrier selection too, and while cheaper options may sound appealing, a long-standing performer such as DC37, which is capable of fostering resilient and long-lasting biofilms, alleviates many long-term maintenance concerns. Based on these benefits, many engineers consider DC37 an ideal carrier for biological treatment on a multitude of wastewater treatment applications.
