In Poland, as well as worldwide, an increase in craft beer production can be observed. In the last several years, more than 150 of such breweries have appeared and according to Polish Brewery Association, their number might ultimately reach 500. Many of them emerge in the areas with no access to a central sewerage system so they have to solve the problem of waste management on their own. The article presents the results of research on the possibility of using a hybrid system for biological treatment of sewage from craft breweries. The sewage came from a craft brewery Waszczukowe located in the Podlaskie province. A laboratory scale model consisted of a trickling filter (TF) (research model Gunt CE701e) and vertical flow constructed wetland (SS-VF). Innovative filling (Certyd produced by LSA company) of TF and SS VF was applied. The conducted study included determining the changes in the sewage parameters during hybrid treatment, as well as TF and SS VF efficiency separately. The aim of the research was to show the possibility of treating sewage to a point when it was possible to discharge it to a receiver, in compliance with the Polish legal regulations. The research results might be used in designing a treatment system or sewage pretreatment in craft breweries. The average efficiency of TF operating with 100% recirculation was 76% for BOD 5 , 80% for COD, 26% for TN and 34% for TP, while the total treatment efficiency of a hybrid system (TF and SS-VF) was 98%, 98%, 72% and 77%, respectively. The load of TF during operation with recirculation was on average 0.38 kg BOD 5 m-2 d-1 , 0.57 kg COD m-2 d-1. The load of SS-VF was on average 0.09 kg BOD 5 m-2 d-1 and 0.12 kg COD m-2 d-1. The obtained results of hybrid treatment permitted to discharge the sewage to the receiver.

“…Also, the reject water from thermophilic aerobic stabilization is characterized by a high concentration of nitrogen and phosphorus. Dąbrowski [17] estimates these values at around 1487 (± 166) g N/m 3 for TKN and 128.5 (± 16.7) g P/m 3 for TP.…”

Most studies on the impact of reject waters recycled from sludge processing in the multi-phase activated sludge process focus on anaerobic sludge treatment in large wastewater treatment plants, leaving apart the processes of aerobic sludge stabilization often used in smaller facilities in rural and suburban areas. The article presents the results of tests carried out in three small and medium-sized wastewater treatment plants with biological removal of biogenic compounds that use aerobic stabilization to process sludge. The research concerned the quantity and quality of reject waters generated in the process of aerobic stabilization and dewatering of sewage sludge and their impact on the multi-phase activated sludge process. The results showed that the average volume of generated reject waters ranged from 3.2 to 5% of the incoming wastewater volume. The average share of organic compounds and total nitrogen loads contained in reject waters did not usually exceed 5–10% of the loads in raw wastewater but reached almost 50% in the case of total phosphorus. Studies indicated that the composition of the supernatant from aerobic stabilization is strongly dependent on the course of the process. The best quality was obtained for cyclic operation of the aerobic stabilization tank with 16 h of aeration and 8 h of settling. The results also showed the negative impact of sudden discharges of reject waters from sludge processing to a multi-phase biological reactor, which can be reduced by using an appropriate equalization tank and pretreatment of the side stream to reduce the recirculation of phosphorus.

“…Mechanical sludge dewatering produces effluent. This liquid may contain a high concentration of organic substances [13], nitrogen and phosphorus [14]. In most wastewater treatment plants, effluent from sludge dewatering, stabilised with both aerobic and anaerobic methods, is directed to treatment together with raw sewage [15,16].…”

“…Due to the high concentration of ammoniacal nitrogen in the effluent, it may be reasonable to use, among others, methods: SHARON (Single Reactor System for High Ammonia Removal Over Nitrite process) [24] and ANAMMOX (Anaerobic Ammonium Oxidation) [25][26][27]. However, using these methods may be economically unjustified in small-scale treatment plants [13]. As an alternative to biological methods, Huang et al [28] suggest that chemical precipitation may prove economically viable to remove ammoniacal nitrogen and phosphorus from supernatants after anaerobic digestion.…”

The study presents the research results on the rejected water generated in dewatering sludge stabilised in Autothermal Thermophilic Aerobic Digestion (ATAD) technology. The research was carried out in three municipal wastewater treatment plants (WWTPs), with a capacity of 1500 to 3260 m3 d−1 and a sludge node capacity of 835 to 2000 kg DM d−1. The mean content of Kjeldahl nitrogen (TKN) in the rejected water samples taken from each object ranged from 485 to 1573 mg N L−1, ammonium nitrogen 318 to 736 mg N L−1, and the average concentration of total phosphorus ranged from 96 to 281 mg P L−1. The average content of organic matter expressed as five-day biological oxygen demand (BOD5) ranged from 205 to 730 mg O2 L−1, while chemical oxygen demand (COD) ranged from 767 to 4884 mg O2 L−1. The study determined the kinetics of the biochemical decomposition of organic matter, assuming that it follows the first-order equation. The average reaction rate constant k in subsequent treatment plants was estimated at 0.424, 0.513 and 0.782 d−1. The R2 coefficient determining the model’s adjustment to empirical values was not lower than 0.952. The organic matter biodegradability index average values ranged from 0.17 to 0.26.
