Tailor made products lead to huge savings
As the AD market has matured it is well known that trace element levels can affect digester performance, causing poor gas production and low methane content if not maintained at the correct levels for good bacterial health.
S ometimes these elements are present in the feedstock, but in most cases there is a deficiency of two or three vital metals. Traditionally a fixed blend was added to cover this shortfall, but this lead to overdosing of some metals, and meant paying for elements there were not needed.
Celtic Chemicals is also a leader in hydrogen sulphide control
Celtic Chemicals Ltd has addressed this issue by tailor making each and every batch to the customer’ s unique requirements based on analysis by a fully independent external laboratory, which we can cross reference with our own in-house analysis to ensure accuracy. This reduces the number of metals down to three or four in many cases and gives savings of up to 50 %. This approach means that changes to feedstock and operation can be rapidly accommodated as a different blend can be made each time. This is especially important at plants with a waste feed stream or with seasonal variations.
Celtic Chemicals is also a leader in hydrogen sulphide control. Using ferric hydroxide in biodegradable sacks, the product is non-toxic and non-hazardous, unlike ferric chloride. The hydroxide also contains much higher levels of iron, up to 50 % compared to 9-14 % in chloride based solutions.
